| 摘 要： | 旋转光楔多重全息术，是利用置于平面参考光波光路上的旋转光楔，调制其传播方向，实现多参考光编码记录获得多重全息图，当用平面波垂直入射再现时，就能从理论上分析出再现像的分布、分离条件及估算的通道数等。这种技术用在全息干涉计量上，就是一种新的多通道全息干涉计量术。本文给出这种新技术在时间平均和双曝全息干涉计量上的应用，并讨论了在单次曝光全息干涉计量（实时法）上的应用。实验结果说明，这种新技术是完全可行的

| Abstract: | A rotating optical wedge multiplex holography is applied to the recording of the multiplex holograms by means of a rotating optical wedge in the plane reference beams in order to modulate the propagation direction and encode multiplex beams. When the hologram is reconstructed by the vertical incident plane beam,the theoretical analysis of the distribution,the separation and number of the reconstructed images can be obtained. The new technique is used in multiplex holographic interferometry.This paper proposes the technical application of time-averaged and double-exposure holographic interferometry and discuss the application of single-exposure interferometry. The expreimental results show that the technique is practicable. |
